As with playback mode, lack of support for CMMFDevSound::Pause() in
DevSound's recording mode causes problems on some devices.
Specifically, while QAudioInput works fine on the Nokia 5800, this
bug was observed on the Nokia N8. This fix means that suspending
and resuming audio input will work correctly on all devices.

When QAudioOutput::suspend() and QAudioOutput::resume() are called
repeatedly, with a short delay between each call, DevSound occasionally
raises a KErrOverflow error. The backend previously translated this
into QAudio::IOError, causing the object to transition into the
QAudio::Stopped state.
This error can be safely ignored, with playback resuming as soon as
more audio data is provided to DevSound. This patch therefore
suppresses the error.

The Symbian backend holds buffers which are passed to it from DevSound,
exposing the memory of these buffers via the QIODevice interface.
When QAudioOutput::resume() is called, the backend re-starts data flow
by passing the buffer it holds back to DevSound. Previously, this
would not happen if the buffer was empty, potentially causing playback
to stall. This patch ensures that the buffer is always sent back to
DevSound, and data flow therefore always resumes.

Because of the logic in the Symbian implementations of suspend()
and processedUSecs(), the behaviour prior to this patch was as follows:
- after calling suspend(), processedUSecs() reported zero
- when resume() is called, the amount of silent padding data inserted into
the output stream is equal to the amount of data played prior to suspend()
The patch corrects the above defect, but introduces a new one, which is
described in QTBUG-9322

Changed backend from being a plugin, to being statically compiled into
QtMultimedia.dll. This is to achieve consistency with the backends for
other plugins, and to allow the plugin API to be modified.
